Abstract: A bush assembly comprising a component having a bore, a bush fitted in the bore and having a flange that extends radially outwardly over a surface of the component surrounding the bore, and a seal assembly for sealing the interface between the flange and the surface of the component, wherein the seal assembly includes a seal member and a layer of sealant between the seal member and the interface between the flange and the surface of the component. Also a method for sealing a bush, a kit of parts for forming a bush assembly, and a clamping tool for forming a bush assembly.

Abstract: A pivot joint assembly has a first part with a hole. A pivot pin passes through the hole. A second part is carried by the pivot pin to be rotatable relative to the first part. A bush has an annular sleeve with an inner face engaging the pivot pin and an outer face engaging a bore wall of the first part. A sealing ring between the bush and the first part. The sealing ring has a body attached to the first part, and a sealing member extending away from the body in a radial direction to a sealing lip which engages the bush without being attached thereto. The sealing member is resiliently compressed to urge the sealing lip towards the bush to maintain engagement with the bush in the event that the bush moves away from the body in the radial direction.

Abstract: A method of sealing a joint between components especially in an aircraft comprises the steps of identifying the sealing gap to be sealed; selecting a suitable sealing material having a fractional maximum sealing thickness and a fractional fully-compressed thickness and selecting a suitable thickness of that sealing material, based on a consideration of the fractional maximum sealing thickness and the fractional fully-compressed thickness of the sealing material and on the sealing gap; locating, between the mating surfaces of the components to be sealed, the suitable thickness of the suitable sealing material; and fastening the components together.

Abstract: A method of assembling components together in sealed relationship and an assembly of two components for forming a fluid-tight seal together are provided. The method includes applying to at least one mating surface a layer of polysulphide sealant and allowing it to cure before bringing together the mating surfaces under a moderate pre-determined pressure for a pre-determined length of time whereby to bring about a sealed joint between the two mating surfaces.

Abstract: A sealing material comprises a partially or fully cured polysulphide sealant and a reinforcing element, especially glass fibre. The sealing material is a flexible solid and is preferably in sheet form. The sealing material is cut to shape like a gasket and is assembled between components to be fastened, for example, in airframe manufacture.

Abstract: A nuclear fusion reactor including a structure for placing at least a portion of a liquid into a tension state, the tension state being below a cavitation threshold of the liquid. The tension state imparts stored energy into the liquid portion. A cavitation initiation source provides energy to the liquid portion sufficient to nucleate at least one bubble having a bubble radius greater than a critical bubble radius of the liquid. A structure for imploding the bubbles produces imploded cavities. The temperature generated by the implosion process can be sufficient to induce a nuclear fusion reaction involving the liquid. A method of providing nuclear fusion tensions a liquid, cavitates the tensioned to form at least one bubble, then implodes the bubble, wherein a resulting temperature is generated that is sufficient to induce a nuclear fusion reaction involving the liquid.
